A 30 kW star-connected synchronous motor is supplied from a 415 volt 50 Hz source. When fully loaded and running at unity power factor the input power is 35 kW. The excitation current under these conditions is 10 A. What will be the value of input power if the load remains constant and the excitation (i) is reduced to 5 A (ii) is increased to 20 A?
